This invention relates to manualot the multiple control type; thepresent application being a division of my copending application, SerialNo. 324,993gflled March 20, 1940; I

Manual reset valves, of the type to which this invention relates;preferably employ electromag netic means for maintaining a main valvemember in open position,5against a bias, only after it i has first beenmanually brought to that position. Such means has particular utility inthe control of fuel to a fluid fuel burner; means responsive to theflame of the burner,'or toa pilot burner theree for, usually then beingprovided for controllingthe energization of the electromagnetic means;The flame responsive means mayfconsist 'of a thermoelectric generatingdevice or a thermal cut-out controlling asuitable source of electricalenergy. Upon extinction or the flame', theelectromagnetic means isdeenergized and the valve closes; manual resetting of the. valve thenbeing required for subsequent operation of the burner.

An object of this invention is toprovide, ina

whereby, a pilot burner can besupplied wit resetting operation ot'themain 11 fuel inthe valve and before outlet chamber, normal]plementalvalve means, within the main valve port so that the fluid canpass thereinto, independently oi the supplementa Other objects andadvantages oi the invention will be found in the description, thedrawing, and r the claims; and, for full vunderstanding oi theinvention, reference may be had toethe following detaileddescription andaccompanying drawing, wherein: l; ,1

If the upper plunger 22 is now moved downwardby be limited only by the scope of the appended claims.

I claim as my invention:

1. In a fluid control valve: a casing having an inlet and a main outletand a partition separating the same, said partition having a portopening therethrough provided at the inlet side of the partition with avalve seatga valve member cooperable with said seat and, biased toclosed position, 'said'valve member'jineluding a portion of magneticmaterial, electromagnetic means coop- I erable with said portion, meansextending to the Fig. 1 gas flow to both of the burners is obstructed eM said electromagnetic means, said electromagnetic pressure on thebutton 28, the rod 34 will be depressed and the member 32 brought intoengageelectromagnetic means is subsequently retracted ment with the topsurface of the lower plunger, as shown in Fig. 2. The supplemental valvemember 35 now being open, gas can flow through .openings 31, bore 35,recess 38 and passageway M to the pilot-burner, where it may be lighted.As-

sumingthat a thermmelectricdeVice, electrically connected to the coilI8, is positioned so as to be heated by the'flame of the pilot burner,after a short period of time current will be generated by the device inan amount suflicient to energize the core, I8 to cause the plungers tobe magnetically held in engagement with each other (th member 32beingconsidered a'spart of the upper plunger) so that when the button 28 isreleased, the lower plungerswill be moved upwardwith the upper plunger,against the force of spring 21 which ob,- vio'usly must-beconsiderablylessthanthat of spring 29; the parts'as'suming the positionsshown in Fig. 3. Itis to be understood that therewill -b e.a magneticforce tending toresist the sl iding of the plungers in the core,but-thatforceis slight If the pilot burner flame is extinguished, uponcessationof current, generation bythe thermoelectric device, the.electromagnet is deenergized and the lower plunger falls under theforce of spring 21,-closing the main valve. Pressure; on

the rod-being released, the supplemental valve 3 member 35 also closes.Fuel supply to bothtthe main and the'pilot burner is thus obstructed;re-

setting of the valve, as hereinbefore described,- being required toinitiate further operation of the energized, the upper plunger ma bemanually moved'both downward and upward without affecting the conditionof the main valve. Only when the pilot burner is alight. and thus asafecondition exists, can the main valve be opened.

While I have herein shownv and described a specific embodiment of-my.invention as appliedto the control of a valve for fiuid fuel burners, itis obvious that my invention has other uses and that modifications maybe made without departing from the spirit thereof. I intend therefore toexterior of said casing formechanically moving means, when energizedbeing effective to magnetically hold said valve memberwhen moved intoengagement with said portion so that when the the valve member is movedtherewith to open position against the force of said bias, said casingalso havinga supplemental outlet, means within said port openingdefining a cup-shaped recess in comparison with the force tending tohold the abutting surface of the plungers together. .Also.-

communicating with saidsupplemental outlet, the mouth of saidrecessbeing so arranged that when said valve member is in engagementwith saidseat. the mouth is closed thereby, the portion of the valvemember which then closes saidmouth having a passage therethroughcommunicating with the inlet of the casing and providing a supplementalvalve seat, a supplemental valve member cooper-able with saidsupplemental seat and biased to closed position, and means engageablebysaid electsomagnetic means in its movement toward said main valvemember for moving said supplemental valve member to open position andfor maintaining it inthat position while the elec tromagnet isenergized.

In a fluid control valve: a casing having an inletand a main outlet and apartition separating-the same, said, partitionhaving a port opening therethrough provided at the inletsideof thepartition with a valveseat, a valve vmembercooperable. with said seatand movable away from and toward thesame, means biasing said-valvemember to closed position, an electromagnetfixed with respect to saidcasing and comprising a cor and an energizing coil therefor, said corehavin a bore therethroughza rially aligned with said valve member, afirstmagnetic plunger connected to said valve member'and' having aportion reciprocable in the adjacent end of said bore, a second magneticplunger reciprocable in the other end of saidbore.-.manual meansoperable exteriorly of the casing for moving said second plunger intoengagement with said first plunger, said core being-adapted whenenergized to cause saidplungerstobe magnetically held together sothatwhensaid; second plunger is subsequently retracted said valve memberis moved to open position; said casing also having asupplementai outlet,means defining a supplemental valve port arranged within saidfirst-mentioned port opening and communicating with said supplementaloutlet, and supplemental valve means associated with said first plungerfor controlling fluid flow from said inlet to said-supplementalvalve'port and operated to open position by the. movement of said secondplunger toward said first plunger and maintained in that. position whilethe plungersare magnetically held together. i
